CAS NO.:1314-56-3
UN NO.:1807
HS Code:28091000
Molecular formula:P2O5
Molecular weight:141.94
Electronic structural formula: 
Properties: White crystals, very deliquescent, density 0.9g/cm3,mp. 580-585C, sublimation temperature 300C, vapor pressure 133.3Pa (384C). May transform to amorphous from under elevated temperature and pressure. Readily absorbs moisture from. Exothermic hydrolysis by water to yield phosphoric acid.
Hazards Identification: Non-flammable. Reacts vigorously with water and water-containing substances like wood or cotton, liberates much heat and may even cause fire. Corrosive to metal. Very irritating. May cause severe burn to eye, skin, mucosa and respiratory tract even at as low as 1mg/cm3.
Fire fighting measures: Wear full protective gear. Do NOT use water directly on fire. Use dry chemical, carbon dioxide, or alcohol-resistant foam.
First aid measures:
Inhalation: Remove from exposure to fresh air immediately. Get medical aid.
Eye: Flush eyes with plenty of water for at least 15 minutes. Ger medical aid.
Skin: Flush skin with plenty of water. Get medical aid.
Labeling: Corrosive
Storage & Handling: Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from water, metals, alkali and flammable substances Handle with care. Keep containers tightly closed. Avoid moisture.
Accidental Release Measures: Wear full protective gear. Neutralize the spills with a mixed solution of sodium bicarbonate and calcium hydroxide.
